During elongation, peptide bonds are formed by the activity of:
Show answer and explanation
Correct answer: Peptidyl transferase
Peptidyl transferase catalyzes peptide bond formation between the growing chain and the incoming amino acid. It is a ribozyme activity carried out by the 23S rRNA in the large ribosomal subunit.
